IMPROVEMENT IN FEED-WATER PIPES.

The Schedule referred to in these Letters Patent and making of the same.

Water in all parts of the boiler equally and simulta' neously in annular sheets or sprays, by means of the graduated perforatious and the conical form of the in addition to relieving the feed-check valve of any pressure from within.

By tbeemployment of puppet-valves the water is distributed equally in a thin sheet all around the valves, as would not be the case with otherforms of check-valve. r

In the accompanying drawing- Figure 1 .represents a longitudinal section.

Figure 2 represents'a top view.

In my drawingp p represent the feed-pipe in the boiler.

'v Iu represent the puppet-valves; and

s s, their seats;

g g, the guards, in which the valve-stems work.

m m is the valve-stem.

Each of the perforations e e, which are made in the pipe at suitable distances, isprovided with a puppetvalve lwith a conical seat.

v The feed-water passes through the feed-checirvalve into the feed-pipe p @and out of the perforations e e,

being separated by the conical form of the valve-seat,

andv distributed throughout the water-space of the boiler in au annular sheet or spray.

These puppet-s are opened by means of the pressure from the feed-check valve, and vwhen the feed-supply is out ofi' the valves return to their respective seats, closing themselves, and resist any pressure external to the pipe p p, thus relieving the feed-check valve of any strain by a retrograde pressure of the feed- Water.

1. A feed-water pipe within a steam-boiler, with graduated perforations to equalize the distribution of v 4thefieed-water in vthe boiler, substantially as and for- .purpose described.

2. A puppet-valve or series of puppet-valves within asteamboiler or a pipe discharging water thereinto, substantially as and for the purpose hereinbefore de'- scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
